SYNTHESIS OF TRICYCLO!3.3.1.13,7!DEC-2-YL!R-(R*,R*)!-3-(1H-INDOL-3-YL-MET HYL)-3-METHYL-4,9-DIOXO-7,11-DIPHENYL-10-OXA-2,5,8-TRIAZA-UN DECANATE

摘要

The invention relates to a simplified process for the preparation of tricyclo[3.3.1.13,7]dec-2-yl [R-(R*,R*)]-3-(1H-indol-3-yl-methyl) -3-methyl-4,9-dioxo-7,11-diphenyl-10-oxa-2,5,8-triazaundecanoate, the essential key compound for the preparation of a new class of CCK inhibitors.
